ok guys here is the deal.. I did a PI headswap on my car and left a plug outta the back of the driver side head and one in the front upper side of the pass. head and I started it up for about 2 minutes when i noticed oil and water going everwhere so I shut the motor off and pulled the heads off again and found that i have had water mix with my oil somehow and I dont know how that could have happened anyone know what might be the cause could it have been a bad sealing headgasket?...please help me
